I had an issue the other day when my engine ('04 Renny) wouldn't shut off even with the key out... I ended up putting it in gear and letting the clutch out until she stalled.
Since then, I've had a check engine light and when I got the codes pulled this morning I ended up with:
462 (Fuel Level Sensor Low Voltage)
480 (Cooling Fan 1 Malfunction)
481 (Cooling Fan 2 Malfunction)
I'm tackling the radiator fan first, but I'm looking for a good way to test the fan to see if the problem is the fan itself, an electrical ground problem, or a problem with the relay. The codes cleared up on my way home from lunch today, so the intermittent nature is making me think relay first (since I've already had to replace my horn relay and all the wiring looks good).
What's the best way to test a radiator fan for proper function?
